Hi Varban, I am now getting random 32-bit values when polling it from the UHD (instead > of a constant that indicates a "zero" reception)
Even with the antenna disconnected you can expect some LSBs to toggle due to inherent receiver noise. 1) How should I interpret the 32-variable? > It is a short complex int where the upper 16-bits are I and the lower 16-bits are Q. > 2) Is the strobe_rx the correct signal that indicates new sample arrival? > Yes > 2) Do I need new_rx_control? No Have I done this correctly in general, or there is something completely > wrong in my approach? What do you want to accomplish?
